IterableProperty<T> constructor

IterableProperty<T>(String name, Iterable<T> value, { Object defaultValue: kNoDefaultValue, String ifNull, String ifEmpty: '[]', DiagnosticsTreeStyle style: DiagnosticsTreeStyle.singleLine, bool showName: true, bool showSeparator: true, DiagnosticLevel level: DiagnosticLevel.info })

Create a diagnostics property for iterables (e.g. lists).

The ifEmpty argument is used to indicate how an iterable value with 0 elements is displayed. If ifEmpty equals null that indicates that an empty iterable value is not interesting to display similar to how defaultValue is used to indicate that a specific concrete value is not interesting to display.

The style, showName, showSeparator, and level arguments must not be null.

Implementation

IterableProperty(
  String name,
  Iterable<T> value, {
  Object defaultValue = kNoDefaultValue,
  String ifNull,
  String ifEmpty = '[]',
  DiagnosticsTreeStyle style = DiagnosticsTreeStyle.singleLine,
  bool showName = true,
  bool showSeparator = true,
  DiagnosticLevel level = DiagnosticLevel.info,
}) : assert(style != null),
     assert(showName != null),
     assert(showSeparator != null),
     assert(level != null),
     super(
  name,
  value,
  defaultValue: defaultValue,
  ifNull: ifNull,
  ifEmpty: ifEmpty,
  style: style,
  showName: showName,
  showSeparator: showSeparator,
  level: level,
);
